Abstract: A fluorescence or luminescence scanner and a method for generating 3D fluorescence or luminescence scans are disclosed. The scanner records a fluorescence and/or luminescence image and an optical image of the body to be examined. A pattern, such as a pattern of stripes or some other geometric pattern, is projected at a first angle onto the body to be examined. As a function of the geometric angles, based on the patterns recorded, 3D location information of each surface point of the scanned body is calculated. Both an optical image and a 3D fluorescence and/or luminescence image are obtained. The mutually superimposed (fused) images can be displayed in the form of a 3D fluorescence or luminescence scan.

At least one surface portion has a filter characteristic such that fluorescent light can pass through, and at least visible light is filtered out. At least one further surface portion has a filter characteristic such that visible light can pass through.

Abstract: The invention relates to a method for repositioning a patient in a diagnostic/therapeutic system, as well as to such a system, wherein a repeated, accurate repositioning is achieved by producing difference images from a reference image and a current image, each in two recording axes, which are independent of each other, and by subsequently minimizing the visible differences. The reference images are produced with the same camera setting as the current images.
